Win98/98SE/ME can't handle more than 512 megs of memory It transpires that Win ME, Win98 and Win95 cannot deal with main memory sizes in excess of 512MB. This problem may occur more readily with Advanced Graphics Port (AGP) video adapters because the AGP aperture is also mapped to addresses in the system arena. For example, if Vcache is using a maximum cache size of 800MB and an AGP video adapter has a 128MB aperture mapped, there is very little address space remaining for the other system code and data that must occupy this range of virtual addresses." And here are the three suggested workarounds: Physically remove any memory in excess of 512MB [!] Use the System Configuration utility to limit the amount of memory that Windows uses to 512MB or less. Use the MaxFileCache setting in the System.ini file to reduce the maximum amount of memory that Vcache uses to 512MB (524,288 KB) or less." And the unspoken fourth solution: upgrade to Windows 2000. Knowledgebase also admits that the addressing restriction has been identified as a failing in Windows. Installing Win2K obviated the problem. All 768MB ran faultlessly.
